This patchset creates an arch_scale_freq_power function for ARM, which is used to set the relative capacity of each core of a big.LITTLE system. It also removes the broken power estimation of x86.
Modification since v3: - Add comments - Add optimization for SMP system - Ensure that capacity of a CPU will be at most 1
Modification since v2: - set_power_scale function becomes static - Rework loop in update_siblings_masks - Remove useless code in parse_dt_topology
Modification since v1: - Add and update explanation about the use of the table and the range of the value - Remove the use of NR_CPUS and use nr_cpu_ids instead - Remove broken power estimation of x86
Peter Zijlstra (1): sched, x86: Remove broken power estimation
Vincent Guittot (4): ARM: topology: Add arch_scale_freq_power function ARM: topology: factorize the update of sibling masks ARM: topology: Update cpu_power according to DT information sched: cpu_power: enable ARCH_POWER
